Handling inventory is about properly managing the processes of procuring, keeping, and selling inventory. This includes the components necessary for making products and the completed goods that are ready for purchase. In the bigger picture of supply chain management, inventory management covers many functions, like controlling stock levels, handling orders, and predicting demand for items.

Inventory management is a pivotal component of a business’s operational framework. It ensures that the delicate balance between supply and demand is meticulously maintained. By employing a systematic approach to managing inventory levels, businesses get to minimize costs associated with holding surplus inventory. It simultaneously ensures that product availability aligns with customer demand. This strategic balance is crucial for maintaining operational efficiency and optimizing financial performance.

What are the Different Types of Inventory Management Systems?

1. Manual Inventory Management System

Before automation technology became mainstream, manual processes dominated the realm of inventory management. Businesses would physically count items to monitor inventory levels, a method fraught with several issues. Despite a significant shift towards automation, several small businesses with minimal inventory levels continue this traditional approach. The procedure typically involves an employee manually checking off items against a list, recording the numbers, and then inputting these figures into a spreadsheet. This crucial data,  not verified by any automated system, forms the basis for making decisions related to inventory management.

2. Periodic Inventory Management System

Serving as a middle ground between the manual and perpetual systems, the periodic inventory management approach offers greater flexibility. It allows for physical counting at set intervals—be it monthly, weekly, or annually. This system is suited to businesses that keep lower inventory levels and have a limited selection of products for sale.

One of the main hurdles companies using the periodic system face is its lack of real-time, detailed tracking. It does not monitor inventory for each transaction. This makes it challenging to pinpoint accounting discrepancies or accurately follow product movements. Such a system complicates the accurate calculation of the Cost of Goods Sold (COGS), posing a significant issue for accurate financial reporting.

3. Perpetual Inventory Management System

The perpetual inventory management system is regarded as the most effective approach for meticulous inventory tracking. It ensures precise monitoring of stock levels and costs with each transaction. Leveraging digital technology, it provides real-time updates on inventory, purchases, and returns, facilitating accurate stock management throughout its lifecycle.

Implementing a perpetual system allows businesses to efficiently identify slow-moving items, pinpoint stock locations, and maintain optimal reorder points. This helps in avoiding issues of understocking or overstocking. It enables business owners to make informed, timely decisions crucial for fostering growth and ensuring profitability. Moreover, the enhanced accuracy in tracking inventory helps in better detection and addressing of problems like theft.

The perpetual system is typically favored by businesses with high sales volumes and diverse inventory.  It simplifies managing the complexities and demands of modern commerce through automated inventory management software, making operations smoother and more efficient.
